INTR ODUCTION

Dear customer!

Cong ratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant. During over 300 years of continuous operation, the Husqvarna factory has produced a lot of different products, from wood stoves to modern kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the ﬁrst motor driven lawn mowers appeared, followed by chain saws in 1959, and it is within this area Husqvarna is working today.

Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our highest priority. We develop, manufacture and market high quality motor driven products for forestry and gardening as well as for building and construction industry.

Your purchase gives you access to professional help with repairs and service whenever this may be necessary. If the retailer who sells your machine is not one of our authorized dealers, ask for the address of your nearest servicing dealer.

It is our wish that you will be satisﬁed with your product and that it will be your companion for a long time. Think of this operator

s manual as a valuable document. By following its ′ content (using, service, maintenance etc) the life span and the second-hand value of the machine can be extended. If you ever lend or sell this machine, make sure that the borrower or buyer gets the operator

be checked. See instructions under the heading Maintenance.

Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached.

WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ﬁngers, hands or wrists. The risk increases at low temperatures.

Stop switch

Use the stop switch to switch off the engine.

Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier.

The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine

′s handle unit.

Mufﬂer

The mufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A mufﬂer ﬁtted with a catalytic converter is also designed to reduce harmful exhaust gases.

In countries that have a warm and dry climate there is a signiﬁcant risk of ﬁre. We therefore ﬁt certain mufﬂers with a spark arrestor screen. Check whether the mufﬂer on your machine is ﬁtted with this kind of screen.

For mufﬂers it is very important that you follow the instructions on checking, maintaining and servicing your machine.

Never use a machine that has a faulty mufﬂer.

8 – English

1155676-49 Rev. 2 2013-03-14

GENERAL SAFETY PRECAUTIONS

Regularly check that the mufﬂer is securely attached to the machine.

If the mufﬂer on your machine is ﬁtted with a spark arrestor screen this must be cleaned regularly. A blocked screen will cause the engine to overheat and may lead to serious damage.

WARNING! Mufﬂers ﬁtted with catalytic converters get very hot during use and

remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of ﬁre!

WARNING! The inside of the mufﬂer contain chemicals that may be

carcinogenic. Avoid contact with these elements in the event of a damaged mufﬂer.

Cutting equipment

This section describes how you can achieve maximum clearing capacity and extend the life of the cutting attachment through correct maintenance and using the right type of cutting attachment.

• Only use cutting equipment recommended by us!

• Keep the chain’s cutting teeth properly

Harness

Check that the harness is not damaged. In an emergency situation, release yourself from machine

and harness according to the following method.

• Maintain the correct raker clearance! Follow our

instructions and use the recommended raker gauge.

Too large a clearance increases the risk of

kickback.

• Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.

GENERAL SAFETY PRECAUTIONS

WARNING! Never use a machine with faulty safety equipment. The machine’s

safety equipment must be checked and maintained as described in this section. If your machine fails any of these checks contact your service agent to get it repaired.

WARNING! Always stop the engine before doing any work on the cutting

attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it.

Speciﬁcation of bar and saw chain

When the cutting attachment supplied with your machine has to be replaced, because it is worn out or damaged, you must only ﬁt the types of bar and saw chain recommended by us.

Guide bar

• Length (inches/cm)

• Number of teeth on bar tip sprocket (T). Small number = small tip radius = low risk of kickback.

• Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket.

• Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links.

• Lubrication hole and hole for the chain tensioner.

• Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket.

10 – English

Saw chain

• Saw chain pitch (inches). (The distance between three drive links, divided by two.)

• Drive link width (mm/inches)

1155676-49 Rev. 2 2013-03-14

• Number of drive links.

GENERAL SAFETY PRECAUTIONS

- Filing angle

Level of kickback reduction. The only thing that describes the level of kickback reduction offered by a saw chain is its model number.

Sharpening your chain and adjusting raker clearance

WARNING! The risk of kickback is increased with a badly sharpened chain!

General information on sharpening cutting teeth

• Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the cuttings will be very small. If the chain is very blunt it will not produce any cuttings at all. Wood powder would be the only result.

• A sharp chain eats its way through the wood and produces long, thick cuttings.

• The cutting part of the chain is called the cutting link and this consists of a cutting tooth (A) and the raker lip (B). The cutting depth is determined by the difference in height between the two.

GENERAL SAFETY PRECAUTIONS

gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.

• File all the teeth to the same length. When the length of the cutting teeth is reduced to 5/32 inch (4 mm) the chain is worn out and should be replaced.

min 4 mm

(0,16”)

WARNING! Departure from the sharpening instructions considerably

increases the risk of kickback.

Sharpening cutting teeth

To sharpen cutting teeth you will need a round ﬁle and a ﬁle gauge.

• Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difﬁcult to sharpen correctly.

• Always ﬁle cutting teeth from the inside face outwards. Reduce the pressure on the return stroke. File all the teeth on one side of the bar ﬁrst. Then turn the saw over and ﬁle the remaining teeth from the other side.

General advice on setting raker clearance

• When you sharpen the cutting teeth you reduce the raker clearance (=cutting depth). To maintain optimal cutting performance you must ﬁle back the raker lip to the recommended height.

• On a low-kickback cutting link the front edge of the raker lip is rounded. It is very important that you maintain this radius or bevel when you adjust the raker clearance.

• We recommend that you use our raker gauge to achieve the correct clearance and bevel on the raker lip.

12 – English

WARNING! The risk of kickback is increased if the raker clearance is too large!

Setting the raker clearance

• Before setting the raker clearance the cutting teeth should be newly sharpened.

1155676-49 Rev. 2 2013-03-14

GENERAL SAFETY PRECAUTIONS

We recommend that you adjust the raker clearance every third time you sharpen the chain. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively.

• To adjust the raker clearance you will need a ﬂat ﬁle and a raker gauge.

• Place the gauge over the raker lip.

• Place the ﬁle over the part of the lip that protrudes through the gauge and ﬁle off the excess. The clearance is correct when you no longer feel any resistance as you draw the ﬁle over the gauge.

Tensioning the chain

WARNING! A slack chain may jump off the bar and cause serious or even fatal

injury.

- Undo the bar nut.

- Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. The chain should be tensioned until it does not sag from the underside of the bar.

- Tighten the bar nut using the combination spanner. Check that the chain can be pulled round easily by hand.

• The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.

• Check the chain tension every time you refuel. NOTE! A new chain has a running-in period during which you should check the tension more frequently.

• Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand.

1155676-49 Rev. 2 2013-03-14

Lubricating cutting equipment

WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries.

Chain oil

• Chain oil must demonstrate good adhesion to the chain and also maintain its ﬂow characteristics regardless of whether it is warm summer or cold winter weather.

• As a chain saw manufacturer we have developed an optimal chain oil which has a vegetable oil base. We recommend the use of our own oil for both maximum chain life and to minimise environmental damage.

• If our own chain oil is not available, standard chain oil is recommended.

English – 13

GENERAL SAFETY PRECAUTIONS

• In areas where oil speciﬁcally for lubrication of saw chains is unavailable, ordinary EP 90 transmission oil may be used.

• Never use waste oil! This is dangerous for yourself, the machine and the environment.

Filling with chain oil

The oil pump is preset at the factory to satisfy most lubrication requirements. A full oil tank normally lasts about the same time as a full fuel tank. Therefore check the amount of oil in the oil tank when ﬁlling the fuel to prevent damage to the saw chain and bar that may arise due to a lack of lubrication.

Checking chain lubrication

• Check the chain lubrication each time you refuel. Aim the tip of the bar at a light coloured surface about 20 cm (8 inches) away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface.

regularly. Turn the adjuster screw anticlockwise to decrease the oil ﬂow.

What to do if lubrication does not work:

• Check that the oil channel in the bar is not obstructed. Clean if necessary.

• Check that the oil channel in the gear housing is clean. Clean if necessary.

• Check that the bar tip sprocket turns freely. If the chain lubrication system is still not working after carrying out the above checks you should contact your service workshop.

Adjusting chain lubrication

When cutting dry or hard species of wood it may be necessary to increase lubrication. Turn the adjuster screw clockwise to increase the oil ﬂow. Remember that this will increase oil consumption, check the level in the oil tank

14 – English

Checking wear on cutting equipment Saw chain

Check the chain daily for:

• Visible cracks in rivets and links.

• Whether the chain is stiff.

1155676-49 Rev. 2 2013-03-14

GENERAL SAFETY PRECAUTIONS

• Whether rivets and links are badly worn.

We recommend you compare the existing chain with a new chain to decide how badly the existing chain is worn.

When the length of the cutting teeth has worn down to only 5/32 inch (4 mm) the chain must be replaced.

min 4 mm

(0,16”)

Chain drive sprocket

Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive.

• Whether the tip of the bar is uneven or badly worn. If a hollow forms on the underside of the bar tip this is due to running with a slack chain.

• To prolong the life of the bar you should turn it over daily.

WARNING! A faulty cutting attachment may increase the risk of accidents.

Guide bar

Check regularly:

• Whether there are burrs on the edges of the bar. Remove these with a ﬁle if necessary.

• Whether the groove in the bar has become badly worn. Replace the bar if necessary.

1155676-49 Rev. 2 2013-03-14

ASSEMBLY

Fitting the cutting head

• Fit the cutting head on the shaft so that the screw (A) is aligned with the hole in the shaft as shown.

The chain should be tensioned until it ﬁts snugly on the underside of the bar.

• Tighten screw A.

• Tighten screw B.

CAUTION! Make sure that the drive shaft inside the shaft engages with the cut-out in the cutting head.

Fitting the bar and chain

Unscrew the bar nut and remove the protective cover. Fit the bar over the bar bolt. Place the bar in its rearmost

position. Place the chain over the drive sprocket and in the groove on the bar. Begin on the top side of the bar.

Make sure that the edges of the cutting links are facing forward on the top edge of the bar.

Fit the cover and locate the chain adjuster pin (A) in the hole in the bar. Check that the drive links of the chain ﬁt correctly on the drive sprocket (B) and that the chain is in the groove in the bar. Tighten the bar nut ﬁnger-tight.

Tension the chain by turning the chain tensioning screw clockwise. Use a combination spanner or turn by hand.

• The chain is correctly tensioned when there is no slack on the underside of the bar, and it can still be turned easily by hand. Tighten the bar nut with the combination spanner while holding up the tip of the bar.

• When ﬁtting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain ensures good cutting performance and long life.

Fitting the impact guard (only some models)

If the machine has a impact guard bolted under the engine this should be removed before the impact guard is assembled.

Fit the guard using the three screws and washers. Fit the two short screws in hole A. Tighten the screws to a torque

FUEL HANDLING

Fuel safety

Never start the machine: 1 If you have spilled fuel on it. Wipe off the spillage and

allow remaining fuel to evaporate.

2 If you have spilled fuel on yourself or your clothes,

change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

3 If the machine is leaking fuel. Check regularly for

leaks from the fuel cap and fuel lines.

Transport and storage

• Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or naked ﬂames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers.

• When storing and transporting fuel always use approved containers intended for this purpose.

• When storing the machine for long periods the fuel tank must be emptied. Contact your local gas station to ﬁnd out where to dispose of excess fuel.

• Ensure the machine is cleaned and that a complete service is carried out before long-term storage.

• The transport guard must always be ﬁtted to the cutting attachment when the machine is being transported or in storage.

• Secure the machine during transport.

• In order to prevent unintentional starting of the engine, the spark plug cap must always be removed during long-term storage, if the machine is not under close supervision and when performing all service measures.

WARNING! Take care when handling fuel. Bear in mind the risk of ﬁre, explosion

and inhaling fumes.

Fuel

CAUTION! The machine is equipped with a two-stroke

engine and must always been run using a mixture of gasoline and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

WARNING! Fuel and fuel fumes are highly inﬂammable and can cause

serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation.

Gasoline

CAUTION! Always use a quality gasoline/oil mixture with

an octane rating of at least 87 octane ((RON+MON)/2). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded gasoline/oil mixture. Leaded gasoline will destroy the catalytic converter.

Use low-emission gasoline, also known as alkylate gasoline, if it is available.

This engine is certiﬁed to operate on unleaded gasoline.

• The lowest recommended octane grade is 87 ((RON+MON)/2). If you run the engine on a lower octane grade than 87 so-called knocking can occur. This gives rise to a high engine temperature and increased bearing load, which can result in serious engine damage.

• When working at continuous high revs a higher octane rating is recommended.

Two-stroke oil

• For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two stroke-engines.

• Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).

• Never use oil intended for four-stroke engines.

• Mixing ratio 1:50 (2%) with HUSQVARNA two-stroke oil.

FUEL HANDLING

Mixing

• Always mix the gasoline and oil in a clean container intended for fuel.

• Always start by ﬁlling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline.

• Mix (shake) the fuel mixture thoroughly before ﬁlling the machine’s fuel tank.

• Do not mix more than one month’s supply of fuel at a time.

WORKING TECHNIQUES

• Use the harness to support the weight of the machine and make it easier to handle.

• If any foreign object is hit or if vibrations occur stop the machine immediately. Disconnect the HT lead from the spark plug. Check that the machine is not damaged. Repair any damage.

• If anything gets caught up in the cutting equipment while you are working, switch off the engine and let it stop completely and remove the ignition lead before cleaning the cutting equipment.

• This machine is not electrically insulated. If the machine touches or comes close to high-voltage power lines it could lead to death or serious bodily injury.

Safety instructions after completing work

• The transport guard should always be ﬁtted to the cutting attachment when the machine is not in use.

• Make sure the cutting attachment has stopped before cleaning, carrying out repairs or an inspection. Disconnect the HT lead from the spark plug.

• Always wear heavy-duty gloves when repairing the cutting attachment. This is extremely sharp and can easily cause cuts.

Basic working techniques

• Hold the machine as close to your body as possible to get the best balance.

• Make sure that the tip does not touch the ground.

• Do not rush the work, but work steadily until all the branches have been cut back cleanly.

• Always slow the engine to idle speed after each working operation. Long periods at full throttle without any load on the engine can lead to serious engine damage.

• Always work at full throttle.

• Let the engine drop back to idle speed between each cut. Long periods at full throttle can cause serious damage to the centrifugal clutch.

WARNING! Never stand directly underneath a branch that is being cut. This could lead to serious or even fatal personal injury.

Observe great care when working close to overhead power lines. Falling branches can result in shortcircuiting.

WARNING! Observe the applicable safety regulations for work in the vicinity of overhead power lines.

• Store the machine out of reach of children.

WORKING TECHNIQUES

WARNING! This machine has a long reach. Make sure that no people or

animals come closer than 15 m when the machine is running. Never swing the machine around without ﬁrst checking behind you to make sure no-one is within the safety zone.

• Whenever possible position yourself so that you can make the cut at right angles to the branch.

90°

• Do not work with the shaft held straight out in front of you (like a ﬁshing rod) as this increases the apparent weight of the cutting attachment.

• Cut large branches in sections so that you have better control over where they fall.

to prevent jamming. Keep the chain running while you withdraw the cutting attachment from the branch to prevent it jamming.

• Use the harness to support the weight of the machine and make it easier to handle.

• Make sure you have a ﬁrm footing and that you can work without being hampered by branches, stones and trees.

WARNING! Never activate the throttle without having the cutting attachment in full view.

• Never cut through the swelling at the root of the branch as this will slow down healing and increase the risk of fungal attack!

• Make an initial cut on the underside of the branch before cutting through the branch. This will prevent tearing of the bark, which could lead to slow healing and cause permanent damage to the tree. The cut should not be deeper than 1/3 of the branch thickness

MAINTENANCE

Carburetor

Your Husqvarna product has been designed and manufactured to speciﬁcations that reduce harmful emissions. After the engine has used 8-10 tanks of fuel the engine will be run-in. To ensure that it continues to run at peak performance and to minimise harmful exhaust emissions after the running-in period, ask your dealer/ service workshop (who will have a rev counter at their disposal) to adjust your carburettor.

Function

• The carburetor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburetor. The air/fuel mixture is adjustable. Correct adjustment is essential to get the best performance from the machine.

• The setting of the carburetor means that the engine is adapted to local conditions, for example, the climate, altitude, fuel and the type of 2-stroke oil.

• The carburetor has three adjustment controls: L = Low speed jet H = High speed jet T = Idle adjustment screw

CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment screw T should be turned anti-clockwise until the cutting attachment stops.

Adjustment of the idle speed

Before any adjustments are made, make sure that the air ﬁlter is clean and the air ﬁlter cover is ﬁtted.

Adjust the idle speed using the idle adjustment screw T, if it is necessary to readjust. First turn the idle adjustment screw T clockwise until the cutting attachment starts to rotate. Then turn the screw anticlockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine will run smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to rotate.

Rec. idle speed: See the Technical data section.

WARNING! If the idle speed cannot be adjusted so that the cutting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.

• The L and H-jets are used to adjust the supply of fuel to match the rate that air is admitted, which is controlled with the throttle. If they are screwed clockwise the air/fuel ratio becomes leaner (less fuel) and if they are turned anti-clockwise the ratio becomes richer (more fuel). A lean mixture gives a higher engine speed and a rich mixture gives a lower engine speed.

• The T-screw regulates the throttle setting at idle speed. If the T-screw is turned clockwise this gives a higher idle speed; turning it anti-clockwise gives a lower idle speed.

Basic setting

• The basic carburetor settings are adjusted during testing at the factory. The basic setting is richer than the optimal setting and should be maintained for the ﬁrst few hours the machine is in use. The carburettor should then be ﬁnely adjusted. Fine adjustment should be carried out by a skilled technician.

26 – English

Mufﬂer

CAUTION! Some mufﬂers are ﬁtted with a catalytic

converter. See chapter on Technical data to see whether your machine is ﬁtted with a catalytic converter.

The mufﬂer is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may

1155676-49 Rev. 2 2013-03-14

MAINTENANCE

cause ﬁre if directed against dry and combustible material.

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.

Some mufﬂers are equipped with a special spark arrestor screen. If your machine has this type of mufﬂer, you should clean the screen at least once a week. This is best done with a wire brush.

On mufﬂers without a catalytic converter the screen should be cleaned weekly, or replaced if necessary. On mufﬂers ﬁtted with a catalytic converter the screen should be checked, and if necessary cleaned, monthly.

screen is damaged it should be replaced.

If the screen is frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the mufﬂer. A blocked screen will cause the machine to overheat and result in damage to the cylinder and piston. See also instructions under the heading Maintenance.

CAUTION! Never use a machine with a defective mufﬂer.

WARNING! Mufﬂers ﬁtted with catalytic converters get very hot during use and

remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of ﬁre!

If the

The cooling system consists of: 1 Air intake on the starter. 2 Fins on the ﬂywheel. 3 Cooling ﬁns on the cylinder. 4 Cylinder cover (directs cold air over the cylinder). Clean the cooling system with a brush once a week, more

often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.

MAINTENANCE

Spark plug

The spark plug condition is inﬂuenced by:

• Incorrect carburetor adjustment.

• An incorrect fuel mixture (too much or incorrect type of oil).

• A dirty air ﬁlter.

These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difﬁculties.

If the machine is low on power, difﬁcult to start or runs poorly at idle speed: always check the spark plug ﬁrst before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.020 inch (0,5 mm). The spark plug should be replaced after about a month in operation or earlier if necessary.

CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/ cylinder. Check that the spark plug is ﬁtted with a suppressor.

Air ﬁlter

Clean the ﬁlter every 25 hours, or more regularly if conditions are exceptionally dusty.

Cleaning the air ﬁlter

Remove the air ﬁlter cover and take out the ﬁlter. Wash it clean in warm, soapy water.

IMPORTANT! Use only HUSQVARNA replacement parts. Use of other brands of replacement parts can cause damage to your unit or injury to the operator or others. Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not speciﬁcally recommended by HUSQVARNA.

Gear

IMPORTANT! All service on the saw head must be carried out by an

authorized Husqvarna dealer. Always use Husqvarna's original grease to prevent damage to the gear in the saw head.

Use grease with part number: 579 06 49-01

The air ﬁlter must be regularly cleaned to remove dust and dirt in order to avoid:

• Carburettor malfunctions

• Starting problems

• Loss of engine power

• Unnecessary wear to engine parts

• Excessive fuel consumption.
